To all whom t may concern.:

Be it known that weQWILLTAir L. BRALEY and HENRY N. FAAs, citizens ofthe United States. residing at Springfield, in 'the county of Clark andState of Ohio, have invented certain new `and useful Improvements in"Cultivators, of which the following is a specification.

This invention relatesto improvements in cultivators. it moreparticularly' relating to single row cultivatorsin which two gangs ofcultivator shovels are employed.

An object of the invention is to provide improved means whereby eachgang of shovels may be raised from the vground independently of theother gang, together with means for changing the center of gravity ofthe machine when such operation takes placeby shifting rearwardly theycarrying wheel upon that side of the machine which supports the gang ofshovels-which has been raised.

A further object of the inventionis to provide improved means forshifting the shovel beams and carrying wheels laterally to cause themachine to follow the cornrow's.

In the accompanying drawings: y

Fig. 1v is a view in perspective looking from the rear of a cultivatorembody-ing the improvements.

Fig. 2 is a side elevation. Fig. 3 is a detail of the axle construction.Fig. 4 is a longitudinal section of the parts shown inFig. 3.

Fig. 5 is a plan view of al portion of the machine. i

Fig. 6 is a side elevation of a `portion of the machine.

f Referring to the drawings, 1 represents a pair of frame members whichhave their forward ends converged and secured to thev tongue 2 and theirrear ends secured to a bracket 3qwhi'ch in turn'is clamped to. a tubularaxle `member y4 by clamping members 5 and bolts16, which-bolts alsosecure in positionthe'brackets 6 to which the seat supporting members 7are fastened. 'A

transversely extending rail 8 isfastened tor the forward ends of thesidefr'ame members 1 through the medium of brackets 9 and a draft bar 10is supported from the rail 8 through the medium of hangers 11,the upper`portion of each of which is of yoke form and has journaled therein ananti-fric- ,tion 11011.12 which rides fon top of the rail 8,

Shovel beams 'are indicated aty 13 and each shovel beam is connected toa head 14 which is pivotally mounted on the draft bar 10.

Each of the carrying wheels 15 is journaled upon the horizontal portion15 of a spindle whichl has a 'vertical portion 15 rigidly secured in asleeve 16 by clamping bolts 17 and rivets 18. Each end of the tubuvi`lar axle 4 has journaledtherein a'transversely-extending horizontalportion 19 of an axle spindle which has alongitudinally-extendingportion 20 and a vertical portion 21 which isjournaledinthe sleeve 16. The part 1 9 Vof the spindle is held againstendwise movementlin the axle by a Cotter pin 19 which extends through anopening 19 in the part 19 which is elongated sufiiciently to permit alimited rotary movement of the spindle part 19 in the axle. Each of thebeams 13 has'extending downwardly from its forward end a rigid arm 22the lower end of which Ais preferably braced from the beam by a bracerod .23. Each ofthe sleeves 16 is pivotal'ly connected withthecorresponding arm 22 by a Yrod 24' which is preferably formed in two'parts 'secured together by bolts'25 so that the length thereof may beadjusted. lf. Y

A rock shaft 26 square kin cross-section has mounted thereon bearingsleeves 27 which are liournaled in brackets 28 secured to the side framemembers 1. A main lever 29 is rigidly secured to one end of this rockshaft and has a pawl 30 which cooperates with the teeth of a curved rackA31. Rigidly secured to the rock shaft is a pair Of brackets 32. onenear each end thereof, 'and to each of these brackets 32 is pivotallyconnected, as at 33, an auxiliary lever 34 which has a .pawl 35cooperating with the teeth 36 0n theupper end of the bracketf VThe lowerend vof each lever 34 has a forwardly-proj ecting arm 37 which isconnected with the cori through the links 24 shift the wheelsrearwardly. the transversely-extending horizontal portions-19 of thewheel axlesturning in the ltubular axle 4 to permit of this movement.If, however, it is desired to raise but one only of the beams, theoperating lever 34C Corresponding to that beam is operated by pullingthe same rearwardly, thereby shifting the carrying wheel l5 on that sideof the machine through the arm Q2 and link 24 attached to the beam whichis raised.

Another feature of the invention is the means which we employ forshifting the beams and carrying` wheels laterally to cause the same tofollow the corn rows, this feature being best illustrated in Figs. 5 and(3. Pivotally connected to each of the extensions i of the seatsupporting member 7 is a foot lever i0 which has pivotally connectedtherewith one end of a link il the opposite end of whichis pivotallyconnected to a pair of toggle jointed levers and 4B at the point oftheir juncture. The lever 43 is pivotally connected to the bracket 9previously referred to while the lever 4Q is pivotally connected to aholt @i4 which is carried by theA bracket secured to the draft bar l0.The upper end of each sleeve i6 has laterally projecting trunnions 4G towhich are secured the rear end of a bifurcated arm eti, the forward endof which is secured to a bead ll pivotally connected with the bracket1l.

By this arrangement the beams and wheels may be shifted in eitherdirection by depressing one or the other of the foot levers 49, so as toshift the draft bar endwise on the rail 8, the toggle-jointedarrangement described furnishing increased power Jfor this shiftingoperation over arrangements previously employed for the purpose and alsoproviding for a greater range of shifting movement.

Also pivoted on the bolt 44 is a beam spacing member 48 which has threearms two of which are connected to the beam heads 14- by the links 49and the other of which is connected to a lever 50 bv a link 5l, thisbeam spacer, however, Jtornaing no part of` our present invention.

Having thus` described our invention, we claim:

l. In a c-ultivator` a pair of pivoted shovel beams, supporting wheels,means for simultaneouslyY raising said `beams and shiftingl said wheelsto'balance the beams when raised; and additional means for raising eachof said beams independently of cach other and shifting the adjacentwheel to balance the beam which has'been raised. 2. In a cultivator, aframe, a pair of supportingl wheels for said frame, a pair of shovelbeams having their forward' ends pivotally connectedwith said frame.devices 'located on said frame for simultaneously raising said beams, anindependent device locatedI on said frame for independently raising saidbeams, and means wlierehywhen both beams are raised both supportingwheels are shifted relatively to the frame and when a single beam israised the adjacent supporting wheel only is shifted relatively to theframe.

3. ln a cultivator, a frame, a pair of supporting wheels for said frame,a pair of shovel beams having their forward yends pivotally connectedwith said frame, a rock shaft supported on said frame, a pair of leverspivotally supported by said shaft and connected with the respectivebeams, whereby each of said beams may be independently aised, togetherwith means for locking said levers to said shaft, a main lever connectedwith said shaft whereby both of said beams may be simultaneouslyvraised, together with means for locking` said main leverv` and means forshifting an adjacent supporting wheel relatively to the frame wheneither one of said beams is raised and for shifting both of said wheelsvrelatively to the frame when both of ysaid beams are raised.

a. In .a cultivator, a frame, a pair of supporting` wheels for saidframe, a spindle for each wheel, a second spindle member rotatablyconnected with said frame and having a swiveled connection with saidfirst spindle, a pair of shovel beams having their forward endspivotally connected with said framev` devices located in said frame forsimultaneously raising said beams, additional devices located on saidframe for independently raising said beams. a rigid arm connected witheach beam near the forward end thereof, a link pivotally connecting saidarm with one of said wheel spindles whereby when both beams are raisedboth supporting wheels are shifted relatively to the frame and when asingle beam is raised the adiacent supporting wheel' only is shiftedrelatively to the frame, i

5. In a cultivator, a. main frame, a pair of supporting wheels for saidframe, each of said wheels being associated with a spindle whichincludes a horizontal portion rotatably connected with said frame, arock shaft supported on said frame, a pair of levers pivotally supportedby said rock shaft and connected with the respective beams, means forlocking said levers to said shaftya main lever connected with saidshaft, ymeans for locking said main leverthe arrangement being such thatwhen said shaft is rocked by said main lever both beams are raised andwhen each individual one or the other of said levers is operated but asingle beam is raised.` a rigid arm connected with the forward end ofeach of said beams,` andl a link connecting eachl of said arms with anadjacent wheel spindle whereby raising of hot-h beam shifts both of saidsupporting wheels and the raising of a single beam shifts only one ofsaid supporting` wheels.

In testimony whereof, we have hereunto set our hands this 18th day ofMay 1923.
